In France May 25, 1935 11 claims. (ci. iol-12s) This invention relates to a machine for printing designs on fabricsby means 'of a perforated surface which permits the .passage of the dye,l

ink', etc.,on1y at the desired places. The two most well-knowexamples of such surfaces are 'stencils and metal platesl cut and perforated to the design. v I

The printing of fabrics by means of such surfacesis generally effected by pinning the fabric inl a stretched condition on a printing table lcovered with felt or the like and printing successively throughout the length of the latter by means of a frame in which the` perforated surface is stretched. The frame being applied to a part of the fabric, the operators spread the dye or ink by means of a. scraper .over the stencil or the like, then raise the frame and shift it further. As will be understood the various applications of the frame should be made at regular intervals carefully marked off in advance. In particular, vwhen printing in several colours, several frames must be applied successively giver the same parts of the fabric and they have to be minutely ,25 spondto the design.

The present Vmachine permits of 'avoiding any y risk'of careless workmanship which the work of displacing and positioning the frame by hand might involve. It ensures, moreover, a considerable saving of time and reduces the number of *workmen required. The machine according to this invention compositioned in order that the-colours will correprises a carriage rolling on rails disposed on the4 I two sides of the table. A detent.mechanism 4 35comprising a. pawl carried by the carriage and pawl detents adjustable along one of therails permits of 'stopping the carriage at a number of different positions over the length of the table.

11. 'I'here is preferably provided a fine adjustment gear on the .carriage to vary the position ofthe pawl and correct small errors in the longitudinal position of the carriage.

4 The latter comprises a stencil or likeframe which an elevating mechanism permits first of raising by one of its sides causing at rst the opposite edge toy pivot on the materialand then .causing fthe whole' frame vto turn 'about an axis located beyond the material and thus. to move laway entirely from the printed fabric.v A retainiing mechanism associated with the lifting mechanism of the frame .ensures that the fabric' does not ,follow the stencil or the like when the frame ""isliftedthisrcaining mechanism being in turn` raised at the proper moment morder to releaseentirely the carriage, finally, the carriage is.`

preferably provided with a dye or ink reservoir which a distributor actuated by control operatedby the operator permits of opening at vthe deired moment .to spread the ink or dye within the rame. l A

0n both longitudinal sides'of the table I,` Figs. 1 to 3, are disposed guide rails 2 and 3 on which runs a carriage 4. `Aa shown in Figs. 2 to 4 rail li is a simple metal bar on which run plain cylindrical rollers 5 serving only as supports, while rai13 is relatively thick and supports rollers 6 having but one lateral flange 1. Cylindrical 'rollers y8 with vertical axes complete^the guiding Censured on one side by flange' 'l as clearly shown in Fig. 4. i The pivot 9 ofv rollers 8 is eccentrically carried by a spindle lscrewed in a sleeve Il vformingl part of carriage l. It will be easily grasped' that by turning moreor less spindle It, roller 8 may be moved nearer to ril 3 and conf sequently any play in the guiding may be taken' up. A lock-nut I2 is nal adjustment.

In front of rail 3 there is arranged an auxiliary rail I3, Fig. 2. made of thin metal and serving to carry detentsli fixed by set screws Il. Figg shows the shape of detents I5. Ihe carriage4 l has a longitudinal bar I6 (Figs. 41 and 8) on which provided for locking the slides a-smail auxiliary carriage lll voperable by a l screw I8 the head `l9 of which `is axially retained in both directions by the maincarriage; The auxiliary carriage Il carries a blade spring 20, the

free end of which is provided with` a stud 2| cooperating with recesses 22 in the pawl detents I5. yIt will be understood that if the detentsare suitably disposed along rail I3, for instance by means 5 of suitable gauges, the operator may, without need for special care, bring the carriage to all the positions previously marked off along the length of the table. It will be incidentally noted that no damage or misadjustment can result for l the pawl mechanism from the carriage being roughly displaced, stud 2l merely travelling over the detent at which the careless operator intended to stop. Screw I9 permits, if necessary, of effecting any required correction without displacing l when the colour is changed (the new stencil may not coincide with the previous one) or when the fabric 23 stretched over table 2| has moved. In the example illustrated it is assumed, for the sake of clearness, that a stencil 24 is being used. No. change is necessary when this stencil is replaced by a perforated plate..

Stencil 24 is held in a wooden frame 25. The latter (Figs. 1, 9 and 10) has two perforated lugs 23 on its side nearest to the operator, said lugs receiving pins 21f; carried by a-bar 29 pivotaily connected at its middle 29 on a small carriage 30 transversely slidable under the action of a screw 3l in a second auxiliary carriage 32 movable over a bar 33 integral with the lifting mechanism described below. A set screw -34 permits of lockin g carriage 32 inposition. The pivot 29 is locked by a mined nut as. 'rne opposite side of frame 2s is provided with two unperforated lugs 35 which, when the frame rests .on the fabric .23, Fig. 3, are' disposed slightly over a transverse bar 31 of the main carriage 4. Bar 31, Fig. 9, has two adjustable stops 38 permitting of preventing lateral displacement of lugs 39. It will be understood that these mechanisms permit of very exactly adjusting frame '25 in position onthe main carriage 4. The lifting mechanism disposed adjacent the operator comprises a longitudinal spindle 39 operated by a hand lever 40 provided with arms 4| connected by links l42Jwith carriages 43 movable in slides 44 forming part of the main carriage 4. The centre of curvature of slides 44 lies substantially along the loweredge of frame 25 opposite the operator. Carriages 43 carry the lifting bar 33 above referred to. v

In normal operative position, Fig. 2, bar 33 is atsuch a height that bar 23 does not touch lugs 26. Frame 25I thus rests freely on the fabric as in hand working. When the operator moves lever 40 he raises carriages 43 and/ bar 33. Bar 29 therefore ,raises lugs 29 and'ths causes frame 25 to pivot around the edge A, Fig. 5, opposite the operator. Lugs36 (Fig. 5) are lowered and reach bar 31 (Fig. 6). From. this moment frame 25 pivots around bar 31 (/Fig. 7) edge A thus rising from the fabric and from table I. Fig. 3 shows the position oi' the parts 'at the end of this lifting movement. The carriage is now freely movable to another position.

In order to retain the fabric on. the table on the frame being lifted there are provided pegs 45, Figs. 1 and 11, mounted on transverse rods 45 fixed to sleeves 41 loose on a longitudinal bar 49 of the main carriage 4.* Each peg 45 encloses a vertical rod 49 axially movable and having an enlarged head 51| pressed by-a spring 5l in a vertical bore inthe peg. It will be understood that y spring 5| pushes head 50 towards the bottom of the bore thus causing the point of rod 49 to prozs :lect downwards When the Pese are lowered on detents I5, which isparticularly desirable either the fabric their weight compresses springs 5| and ensures a regular pressure of rods 49 on the fabric. Pegs 45 are locked in position on rods 45 by means of set screws 52 and they are disposed so as to ensure a regular pressure. y

Rods 46 terminate/,above the lifting bar 33. In operative position, Fig. l2, rods 49 bear on the table. When the operator operates the lifting lever 40 bar 33 moves over a considerable part of its stroke without touching rods 46, Fig. 13. This first movement corresponds to the separation of the stencil' from the fabric. Then bar 33 raises rods 45 and pegs 45 thus clearing the fabric of rods 49.

.Bar 43 also carries the dye or ink reservoir 53, Figs. 1, 15, 16. The latter has an inclined base 54 provided at its lowest portion with holes 55. These holes are normally closed by a slide 56 held against them by springs 51 which simultaneously force the slide 56 into its closing position. Links 59 connected at one end to slide 56 and at the other end to crank disks 59 keyed on an operating spindle permit of opening slide 56 against the action of springs 51. Spindle 60, Fig. 1, terminates into an operating arm 6I connected to a connecting rod 62 which the operator can easily operate through the medium of an operating lever 53,. It will be easily understood from Fig. 2 that as soon as holes 5,5 are uncovered the dye or ink falls into frame `'25. The operator needsthen only pass a scraper over the stencil to effect the printing.

As will be seenl the machine according to the invention ensures an easy and rapid work and eliminates all risk of error or of incorrect posi'- Apermits with a limited stock of parts, of forming every size of carriage by cutting off the tubes to the proper lengths. The" parts themselves are secured on the tubes either by locking collars or by seit screws, which does not involve any particular machining of the tubes.
